Nothing like some good ole blue blazer, what-we-do-to-protect-par humor (from Leonard Shapiro's Washington Post story):
But beyond about seven yards from the first cut, all the way to the spectator ropes, the USGA wants the grass to be between five and six inches, maybe longer. In that sort of spinach, players likely will only be able to hack the ball out into the fairway with a wedge.
"The idea of adjusting the rough is to make it appropriate for the shot they hit," said Walter Driver, the new president of the USGA. "A player who hits it 15 yards out of the fairway, well, let's just say their sense of humor is going to be tested."
